GTA IV might be scheduled to be released on the 360 and PS3 at the same time, but it seems that Microsoft has managed to secure some exclusive content that is to be released via Xbox Live!

In a recent X06 announcement today, the content will be available a short time after the game is initially released in two "chapters." Each chapter is said to contain approximately 10+ hours of gameplay with new and unique content not accessible through the standard version of the game.

The release date is set for North America on Oct. 16 and Europe on Oct. 19. As of this announcement there is no scheduled release date for the episodic content.
